Unraveling Prolog Assignments: A Journey into Logic
In the realm of academia, Prolog assignments stand as bastions of challenge, testing one's ability to navigate through logic mazes and emerge victorious. Let's embark on this odyssey together, armed with intellect and fortified with expertise.
Question 1: Family Relations in Prolog
Consider a scenario where we aim to represent family relations using Prolog predicates. Define predicates for parent, male, female, sibling, and ancestor, and demonstrate their usage in the following family tree:
male(john).
male(david).
male(peter).
male(mark).
female(susan).
female(emma).
parent(john, susan).
parent(susan, emma).
parent(david, peter).
parent(susan, mark).
Solution:
male(john).
male(david).
male(peter).
male(mark).
female(susan).
female(emma).
parent(john, susan).
parent(susan, emma).
parent(david, peter).
parent(susan, mark).
sibling(X, Y) :-
parent(Z, X),
parent(Z, Y),
X \= Y.
ancestor(X, Y) :-
parent(X, Y).
ancestor(X, Y) :-
parent(X, Z),
ancestor(Z, Y).
In this solution, we define predicates for male, female, and parent. We then define sibling to find individuals who share the same parent, and ancestor to find all ancestors of a given individual.
Question 2: Resolving Logical Puzzles
Let's venture into the realm of logical puzzles, a domain where Prolog shines brightly. Consider the classic "Einstein's Riddle", where five houses of different colors are inhabited by people of different nationalities, each of whom has a different pet, smokes a different brand of cigar, and drinks a different beverage. Using Prolog, solve the puzzle and find out who owns the fish.
Solution:
% Define predicates for different properties
color(red).
color(green).
color(blue).
color(yellow).
color(white).
nationality(english).
nationality(spanish).
nationality(ukrainian).
nationality(norwegian).
nationality(japanese).
pet(dog).
pet(snail).
pet(zebra).
pet(fox).
pet(horse).
cigar(luckystrike).
cigar(parliament).
cigar(kools).
cigar(chesterfield).
cigar(oldgold).
drink(tea).
drink(orangejuice).
drink(milk).
drink(water).
drink(coffee).
% Define the rules and constraints
neighbor(A, B) :- abs(A-B) =:= 1.
left(A, B) :- B is A + 1.
middle(A) :- A =:= 3.
solve(FishOwner) :-
% Define the houses with their properties
Houses = [house(_, _, _, _, _), house(_, _, _, _, _), house(_, _, _, _, _), house(_, _, _, _, _), house(_, _, _, _, _)],
% Assign properties to houses
member(house(red, english, _, _, _), Houses),
member(house(_, spanish, dog, _, _), Houses),
member(house(_, _, _, coffee, green), Houses),
member(house(_, ukrainian, _, tea, _), Houses),
neighbor(house(green, _, _, _, _), house(white, _, _, _, _), Houses),
member(house(_, _, snail, _, yellow), Houses),
member(house(_, _, _, orangejuice, middle), Houses),
member(house(_, japanese, _, _, _), Houses),
neighbor(house(_, _, _, _, blue), house(_, norwegian, _, _, _), Houses),
member(house(_, FishOwner, fish, _, _), Houses).
% Usage: solve(X).
% This will find the owner of the fish.
In this solution, we define predicates for different properties like color, nationality, pet, cigar, and drink. We then impose constraints and rules to deduce the solution, finding out who owns the fish in Einstein's Riddle.
